Love in the Mask

My specialty! ummm let's see:

http://www.mangago.zone/read-manga/ssg_meimon_danshikou_keppuuroku/ (About a girl who joins an elite all-boys school instead of her brother for a year because he got hospitalized. She gets caught up in a mess with a group of guys who believe that she's the reincarnation of the leader of the shinsengumi Kondou Isami.

http://www.mangago.zone/read-manga/classi9/ ( A girl travels to vienna trying to join a famous music school to become a composer. Little did she know that the school is an all-boys school. Btw, this story is a parody of famous musicians from history, Beethoven, Mozart, Chopin, etc. It's hilarious. A must read.
